Solution

1. Preparation

Gather tools and materials: jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, replacement brake pads and rotors (if necessary).
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper mounting bolts with a socket set.
Slide the caliper off the rotor and support it with a bungee cord or similar tool, avoiding tension on the brake line.
Remove the old brake pads from the caliper bracket.
If replacing, compare the new pads with the old ones for correct fit.
Apply brake grease to the back of the new brake pads and any contact points.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for any signs of wear. If scored or warped, remove the rotor by unscrewing its mounting screws.
Clean the hub surface to ensure proper seating of the new rotor.
Install the new rotor, securing it with the screws.

5. Reassemble

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the specified torque (consult the service manual for the exact value).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Final Checks

Remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications in a crisscross pattern.
Pump the brake pedal a few times to seat the pads before driving.
